ychange the direction of its throw'.

lleretoi'ore various kinds of lawn sprinklers have been devised but it`has not been usual to provide means for continuously changing theposition of the spraying nozzle so that it will deliver water in aplurality of directions in succession but in anv irregular sequence.

The object of this invention is to provide means adapted to cause thesprinkling nozzle to move about with a gyratory motion to successivelydischarge tlie water in difierent directions and thereby wet a largerarea than has here ofore been possible with a nozzle of this character.

It is also an object of this invention to provide a very cheap andsimple construction adapted to be connected to an ordinary garden hoseor other source of water supply and under the action of the water'pressure to move about and throw water iii an irregular `course andthereby produce a novel and 'amusing eilect.

The invention consists of the matters hereinafter described in thespeciiication and more fully pointed out and defined in the appendedclaims.`

In the drawings: The figure is a fragmen tary, side elevation'of radevice embed ing in y invention and showing in dotted iiies some of thevarious positions assumed by the distributing or spraying nozzle.

As shown in said drawings: A. indicates the end of a garden hose orother source of water supply, to which is attached by means of anysuitable hose coupling VB a noz-- zle e, which is restricted or taperedat. its Connected at one end to said tapered end c is a i'leiiible pipeC of rubber or any other preferred material and which as shown isprovided with a plurality of spiral coi'rugations c.

of said pipe C is 4attached a connection C to which is engaged a bellshaped distributing nozzle D, theA mouth or larger end of which isclosed by a plate d having a plurality of perforations d near itscircumfen ence but closed at its center.

The operation is follows; When the des vice is attacl'ied` to 'thesourc'c of supply and the water turned thereinto, the distributingnozzle D and the pipe C are filled with water under pressure. The waterentering the pipe C from the restricted nozzle e is directed axially oi'said pipe and therefore.

tends to create a vacuum oi' to reduce pressure at the end of saidnozzle and adjacent the walls ci said pipe.- This unequal ressure causesthe pipe C to move laterally4 at this point owing to its spirallycorrugated form, which motion is accentuated by the Patented July 20,199.

pressure throughthe pipe acting on the eor-l rugated walls, and saidpipe C is thus caused to gyrate and move the nozzle D in variousdirections Obviously a sprinkler constructed in ac cordance with myinvention is adapted to cover a maximum amount of area and to produce avery pleasing and amusing ellect to the eye. Obviously also many detailsof form and construction may be varied without departing` from theprinciples of my in venticn.
